Training School 5

Use and characterisation of new acoustic treatments and tools

Budapest (Hungary), 16-18 December 2019


DENORMS Action’s 5th Training School “Use and characterisation of new acoustic treatments and tools” will be held from 16th to 18th December 2019 in Budapest (Hungary), organised by Óbuda University.

This Training school is aimed at the industrial partners and Early Career Investigators. The training will be offered in both theoretical and experimental aspects of developing new sound absorbing and sound controlling structures.

During the first day, the refresher training courses will be organised covering the basic theory of sound interaction with porous materials and metamaterials. During the following two days lectures and practical sessions will familiarise the audience with the new methods used in design of conventional and metamaterial based noise reducing treatments.

Transport Connections

Airport connections

Budapest city center can be reached from the Airport by public transportation. Bus line 200E operates day and night between Terminal 2 and Nagyvárad tér metro station (the temporary terminus of metro line M3 during reconstruction*). BKK tickets, multi-day travelcards or passes are required for travel. More information on

Another possibility is Ferihegy transzfer

Workshop 8 – Final event

DENORMS Action Final event and dissemination

Coimbra (PRT) – Feruary 2020


This Workshop will be jointly organized with the final event of the DENORMS Action around 4 specific actions.

First, selected members, who benefited from STSM and preferably ECI, PhD candidate and women from ITC, will present their work to the network members during a day.

Second, the results of the Round Robin Tests (mechanical characterization of poroelastic materials, low frequency measurement in reverberant rooms, and low frequency measurement of absorption coefficient) will be presented and disseminated to Action members, policy makers and people involved in the standardization of measurement methods.

Third, results arising from the Action will be presented on a public place in the city in order to increase the visibility and attract student in the field.

Finally, some materials and structures, which are usually good looking, arising from the Action and also coming from all around the world will be exposed in the Science and Technology Museum and presented to public as well as to visiting children from local schools (interpreters are expected).

The last MC meeting will also takes place during this event, during which we will take stock of the Action, the MC member will provide feedback on the Action, and the future Actions will be discussed.

60 participants are expected (40 of which will be funded, the decision about funding will be made by the Organising Committee).


Workshop 7


Second edition of the « Symposium on Acoustic Metamaterials » (SAM)

The second edition of the « Symposium on Acoustic Metamaterials” (SAM) took place from 9th to 11th October 2019 in Ischia (Italy) and was organised by YRAM (Young Researchers in Acoustic Metamaterials), COST Action DENORMS CA 15125 and the University of Salerno.

This second Symposium on Acoustic Metamaterials was targeted to PhD candidates, Early Career Investigators (i.e. researcher whose career spun less than 8 years since the date of the PhD) and aimed at sharing new advances and breakthroughs as well as fostering the community of young researchers in the field of acoustic metamaterials. The second SAM was organised around 6 different sessions comprising 20 min talks and plenary lectures.

More information can be found on the SAM website.
